SMC_KEY(9)

🎀 SMC_KEY(9) 🎀

okay bestie, this is from the Kernel API Manual, and we're about to make FourCC SMC keys make sense. 💅

🌸 NAME 🌸

SMC_KEY — convert FourCC SMC keys in source code to smc_key. periodt. ✨

✨ SYNOPSIS ✨

SMC_KEY (s );

🦋 ARGUMENTS 🦋

• s — the FourCC SMC key that's getting converted. that's the whole argument, bestie. 🫶

💖 DESCRIPTION 💖

This macro is literally your little shortcut for defining FourCC SMC keys in source code and converting them to u32 / smc_key. Like, SMC_KEY(NTAP) will expand to 0x4e544150. no cap, that's the flex. ✨
